f Application med marchado, 1927. semina. 179,499. E

This 'invention relates to clutch 'pedal control devices formotorfvehicles and particuf out of engagement'- andto retain the pedalin such position or .may be operated to swing the clutch'pedal' tothrow'the clutch out/of lthe following description ffinade engagementand to lsets-thev brakes of thev tractor and to retain the clutch pedalin such position;v

These andother objects and advantagesV of.

theinvention will more fully appear from tion" Ywith `'the accompanying'drawings,

wherein Alike reference charactersreferv to the saineor'similar p .artsithroughout the var1.

` 1s`.looped atits upper end to form a keeper ous views and, in which,

1 Fig.2-is av` plan View of certain of the parts illustrated in Fig. l;

1 Fig. 3 is a 'vert-ical section taken on `thev lined-3 FigQ, asindicated bythe arrows' Y Fig; at is ahorizontal section taken on theline'lrty 'of Fig; 8,- as indicated -by the f. arrows,`and,V l tf i yFigf is a vertical sectiontaken on the line 5-.-5 of Fig. 3, asvindicated by the arrows." Y

'Referring-to the` drawings, certain por-` tionsv oialtractorv of thecommonl Fordson type are illustrated, including the housing 6, dash'f?,yspring drivers seat 8, clutch pedal shaft@ Vand clutchv pedal"10. Thesaid parts are of corninon constructionandl are well normallybe' heldupwardly as by spring ten-k sion so' that the: normal position of theclutchpedal 10, whenl the clutch isinengagerrient, will be that`illustrated 1nl full linesin "Fig 1'. To throw the clutch out of inconnec known in'the'artjf'lhe clutchpedal 10 will engagement, the pedall0 must be depressed by' swinging the vsaine downwardly and for-Av"wardly to the 'positionillustrated' inthe upper set of -dotted lines,Fig. l. 1 To throw,v

the clutch' out of engagement and to set vthe brakes of the tractor, theclutch pedal 10 must bey depressed to theposition illustrated in thelower dotted lines Fig. 1. ln accordance with the present` invention, abar 11 formed from strapiron vis provided having atits lower end a shortdiagotogetherby bolts 14j Themain portionl'of barllg'extends 'upwardly'and rearwardly frein/pedal 10 and offset portion llfjand 11b.1AsmallrollerV 15 is carried ;in the keeper 11b adj acent the lower sidethereofby afstud v16 extending through the walls` of thekeeper. ,The dash 7 ofthe tractor isj provided with bolts 7a andpivoted -to said dash by oneof said bolts, preferablyV the lowest bolta hand lever 17 is provided.vrl`he lever 17, rearwardly from. its pivotedr 'end, iszfirstbentoutwardly andthen rearward-ly. and thelever extends through thekeeper-11b, the ylower edge of the lei/'er resting upon the roller 15and the roller being adapted toride lonithe lower edge 'of the l'evei-rrTwo ormo'respaced rearwardly inclined notches 17'a and 17h respectively,are formed in the lower edge of leverv17, while a .handle portion isprovideda't the rear end Vofthe lever.

Lever 17 whenclutch pedal 10 is in raised position, as .indicatedin4full lines Fig; l," extends substantially horizontally and the handleportion of the lever lies closely adj acent the spring drivers seat 8,so that-the,

ysaine 'can be readily Aoperated by the driver -nally bent and laterallyoi'set portion' 11?-- tof so y

of the tractor. V\7lienV it is'- desired to throw Y tlie'clutch of thetractor' out of engagement, lever@ 17 is merely grasped and swungdownwardly thereby causing bar 11 to move down-l lower side of saidkeeper portion and to form f an acute angle with said bar, the sides ofthe l when said lever has been pressed downwardly, to retain the clutchpedal 'in downward position. l y 7. The combination with a clutch pedalof la motor vehicle which is adapted to be swung downwardly andforwardly to throw they clutch of the vehicle'out of engagement, of abar rigidly connected to said clutch pedal and projecting upwardly andrearwardly therefrom, said bar having a keeper portion formed thereinadjacent its upper end, and a lever suitable pivoted forwardly of thekeeper portion of said bar andv extending lthrough the keeper portion ofsaid bar, said bar being adapted t9 ride rearwardly on said lever as thesame is depressed, thereby swinging said clutch pedal downwardly andforwardly to throw the same out of engagement.

8. The structure defined in claim 7, and means for holding theclutch-pedal in downwardly and forwardly pressed position.

9. The combination with 'a clutch pedal of l va motor vehicle, whichv isadaptedto be swung downwardly and forwardly tol throw the clutch out` ofengagement, of a bar rigidly I secured to said clutch pedal, extendingupwardly andrearwardly therefrom and havkeeper, and a lever'pivotallysecured for'- wardly of said keeper and extending therethrough, said.roller being adapted to ride upon the lower edge of said lever, wherebyas said lever is swung downwardlysaid bar will force said clutch pedaldownwardlyand forwardly to throw the clutch out of engage-v ment, saidbar riding rearwardly, saidlever having a notch therein `withwhioh saidroller isvadapted to engage when said bar has reached a given rearwardposition..` y

l0. The combinationwith a clutch pedal of av motor vehicle, which isyadapted to be swung downwardly and forwardly to throw the clutch ofthevehicle out of engagement,

v4o ing a keeper formed adjacent its upper end, v a roller within thelower portion of said of a bar extending upwardly and rearwardly fromsaid clutch pedal, a clamp rigidly securing said bar to said clutchpedal, said bar having a keeperportion formed therein at its upper end,a roller within said keeper' portion, a lever'pivoted forwardly of saidkeeper portion and extending through said keeper portioinsaid barhaving. a notch therein within which said roller is adapted to beengaged, whereby when said lever is i swung Vdownwardly said bar will beswung ydownwardly to swing the clutch pedal downwardly and forwardly tothrow the clutch out of engagement and the upper end of said bar will bemoved rearwardlyin'respect tov said lever until said roller isengagedwith said notch. p f
